1996 GMC suburban 1500 rear diff

I blew the rear diff last week and i Have pulled it apart and its a mess

The crown wheel and pinion are the only parts not damaged i am trying to locate parts here in Sydney and around OZ but no luck so far I can buy the complete centre for $1500 but as i am a mechanic i can rebuild the diff no problems.

Can anyone suggest a site where i can get a rebuild kit as well as the centre sphere which houses the planetry and sun gears as its not repairable .

Try these guys, I ordered and recieved parts from them a few years ago when I was stationed in Italy so I know they ship overseas. Thier a very reputable company with great service.http://www.ringpinion.com/
